Well, the cat is going to be out of the bag soon now. When they try to file and claim her, their e-file will be rejected because her SSN has already been filed on a tax return. Get ready for a talk with the in-laws.
You could still amend and change to filing MFS if you really need to --- but amending takes about 4 months And you cannot amend until your return has been fully processed. So....good luck and Best Wishes.
